Does anyone know the Breed name of the dog I'm going to describe ? They are tiny only weighing about 5 lbs , with reddi

Only weighing about 5 lbs with reddish, wiry fur. And look like little foxes with pointy noses. They are usually active little dogs. I thought they were Wire-haired Fox Terriers. But cannot find any dogs that look like this. Anyone know the Breed name or to obtain any information about them? Thanks!
